We investigated the relationship between sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) while awake as well as mortality. Eighty-nine consecutive outpatients (29 females) with congestive heart failure (CHF; left ventricular ejection fraction, LVEF <45%) were prospectively evaluated. The presence of SDB and of CSR while awake before sleep onset was investigated by polysomno...

This study examined risk factors for sleep-disordered breathing (SDB) in children and adolescents; specifically, quantifying risk associated with obesity, race, and upper and lower respiratory problems. Subjects were participants in a genetic-epidemiologic study of SDB and included 399 children and adolescents 2 to 18 yr of age, recruited as members of families with a member (a proband) with kn...

INTRODUCTION The objective of this study was to identify the clinical predictors for hypertension and sleepiness in an Asian population with sleep-disordered breathing (SDB). MATERIALS AND METHODS This is a retrospective, consecutive case series of 228 patients with symptoms of SDB referred to a tertiary level sleep disorders unit. A full sleep history, body mass index (BMI), Epworth Sleepine...

Previous studies have documented an association between markers of sleep-disordered breathing (SDB) and metabolic syndrome. However, it is not clear if there are gender or ethnic differences in this association. We examined 6,122 participants aged ≥20 years from the National Health and Nutrition Examination Survey 2005-08. Metabolic syndrome was defined as the presence of ≥3 of the following co...

BACKGROUND Sleep disordered breathing (SDB) such as sleep apnea is associated with cardiovascular disease in the general population. However, little is known about the cardiovascular risks of SDB in patients with end-stage renal disease (ESRD). METHODS We identified Medicare fee-for-service beneficiaries aged ≥67 years initiating dialysis between 2004 and 2009. Outcomes of interest included a...

AIMS Recent studies have suggested an emerging link between sleep apnoea and atrial fibrillation (AF). These studies included patients with reduced left ventricular (LV) function which may cause both AF and sleep disordered breathing (SDB). We examined the prevalence of SDB in a population of patients with AF and normal LV function. METHODS AND RESULTS Ninety patients with paroxysmal or persi...

BACKGROUND In the absence of formal polysomnography (PSG), many children with symptoms of sleep-disordered breathing (SDB) go unrecognized and thus may be at risk for perioperative respiratory adverse events (PRAE). OBJECTIVES To develop a simple practical tool to identify children with symptoms consistent with SDB who may be at risk for PRAE. METHODS Three-hundred and thirty-seven parents ...

OBJECTIVES We wanted to evaluate whether the presence of nasal obstruction makes a change on the association between the modified Mallampati score and the severity of sleep-disordered breathing (SDB) and the sleep quality. METHODS Polysomnography (PSG), the modified Mallampati score (MMS), the body-mass index, and a questionnaire about nasal obstruction were acquired from 275 suspected SDB pa...
